Hi again, sorry this took so long. With this patch I can reproducably
hang the system. I know now that the Xserver is getting stuck in
R128CCEWaitForIdle(). The backtrace is below. The question is: what
does it mean? Is it that the DRM driver sent a command that really got
the CCE stuck, or is it that the Xserver is interfering in a way that
it broken something.
I know the ioctl() keeps returning -EBUSY and that the client app
(samples/depth) is waiting in a select() for the X server.
Any hints on how to debug this?
Thanks in advance,
